Document Type and Number:

Japanese Patent JP5409678

Kind Code:

B2

Abstract:

An electric motor control apparatus capable of controlling a motor normally regardless of failures is obtained without increased cost. The apparatus includes a position sensor failure determination unit which outputs a failure determination signal, and generates a first phase; a motor rotation speed calculator which operates based on the failure determination signal and position sensor signals; a phase command generator producing a phase command based on the first phase, the failure determination signal and rotation speed; an amplitude command generator that generates an amplitude command indicating magnitude of a driving signal for the motor, and an electrical energization unit that applies the driving signal to the motor based on the phase command and the amplitude command. Upon failure of a position sensor, the phase command generator generates the phase command using the first phase, and a second phase obtained based on the first phase and the rotation speed.
